MobileFire Extinguishers are produced specifcally for use with Aqueous Film FormingFoam (AFFF 6%) which is remarkably effective when fighting Class B (flammablefuel) fires. The unique section of AFFF stems from it's ability to make waterfloat on flammable fuels.
Theflame quenching foam blanket rapidly spreads over the surface of the fuel andthe aqueous solution floats over the surface to provide a vapour seal. Thisaqueous film foaming action enhances the extinguishment and prevents reflash ofthe fuel.
